hi, thiago,

I have two question:

1. About "qdbus": I can't find "qdbus" in the dbus folder. I find a executable "qdbus" in the /use/local/Trolltech/Qt 4.6.2(the full setup path of qt-x11) On Ubuntu. I download the "qdbus" to the ARM board. Then run it, please refer to the attachment "qdbus".

2. On Windows: I only need include the "dbus-daemon" and "session.conf" in my Qt project in order to using D-Bus. On ARM, Should I include the full dbus folder?  I think it's unreasonable that the dbus will take up so much memory in the limited memory of ARM board. It's my superficial opinion to D-Bus, please correct me.

Thanks very much!

Hello

Please start the daemon, then run the following steps in the same shell you 
start the daemon from, and paste the results here:

	echo $DBUS_SESSION_BUS_ADDRESS
	qdbus
	dbus-send --dest=org.freedesktop.DBus --print-reply / 
org.freedesktop.DBus.ListNames

(the third one is one single line)

Also, please provide the versions of Qt and libdbus-1 you have installed, as 
well as the full path to libdbus-1.so.3.
